Microcomputer 4 is provided as the system controller of CD drive 1.By carrying out the handling procedure that is installed in advance in the CD drive 1, and by providing by the user at the signal of the enterprising line operate of control panel (not shown) or provide the various signals that detect by AFE (analog front end) piece 16, the operation of microcomputer 4 each component block of control.More particularly, tracking error signal and the focus error signal that is detected by AFE (analog front end) piece 16 is provided for microcomputer 4, follow the tracks of and the focus control activation bit to produce, and these conversion of signals are become simulating signal by DVD signal processor 14, again these simulating signals are offered amplidyne generator 18, amplidyne generator 18 is controlled the tracking and the focusing of shaven head 19 successively.By the heading information that is detected by heading information processor 7 is provided, microcomputer 4 will detect the position of the laser beam of being throwed, produce thread controlling and driving information according to testing result, and this information is offered DVD message handler 14, thereby search for and similar operation.Similarly, microcomputer 4 also will carry out main shaft control.

The basic operation of 4 pairs of CDs 2 of microcomputer has been described above.At this, the read data that microcomputer 4 is performed and the operation of write data are described after having started CD drive 1 with reference to the process flow diagram among Fig. 5.In step SP1, start CD drive 1.Then, microcomputer 4 proceeds to SP2 from step SP1, and at this, it will judge whether CD 2 suitably is arranged in the CD drive 1 according to the testing result from the CD 2 of detection means (not shown).If the judged result in step SP2 is (promptly CD 2 suitably not being provided with) of negating, microcomputer 4 will repeat the operation in step SP2.In contrast, if start the CD drive 1 of having loaded CD 2, perhaps after starting CD drive 1, put into CD 2, promptly, if above-mentioned judged result is sure (being that CD 2 suitably is provided with), then microcomputer 4 will proceed to SP3 from step SP2.When should be noted that the operation that repeats in step SP2 at microcomputer 4, if turn-off CD drive 1, microcomputer 4 will directly carry out step SP4, and withdraw from this reproduction or recording process (cutting off (power off)) at this.

In step SP3, microcomputer 4 drive thread motors 21 so that shaven head 19 is moved on the interior circumference of CD 2, and provide the result who reads the inner periphery district of CD from DVD signal processor 14 to microcomputer 4.If CD 2 is final CDs handling, then microcomputer 4 will obtain data the VMG district from DVD signal processor 14.In contrast, if CD 2 is not a CD of final processing, then microcomputer 4 will obtain information the RMA district from DVD signal processor 14.If microcomputer 4 has been recorded in the real-time data record district of CD 2 according to the information specified data in the RMA district, it just searches CD 2 so that obtain VTSI and VTSTT VOBS data in each VTS.Like this, as record in CD drive with reproduce common DVD, microcomputer 4 will obtain to be write data on the CD 2 and the needed management information of reading of data from the CD 2.

In this process, microcomputer 4 obtains in VMG district and the data in the UDF district.When reading the real-time data record district, if can find any intermediate management information that is recorded in the real-time data record district, then microcomputer 4 also obtains intermediate management information.Like this, microcomputer 4 also obtains the management information that is not with the extendfile of DVD video format definition, so that can read extendfile from CD 2.Microcomputer 4 will write down and preserve a series of management information that gets access to like this in built-in storer.

Then, microcomputer 4 enters step SP5, and at this, it will judge whether to be instructed ejects CD 2.If the result who judges is sure, then microcomputer 4 will instruct and load device (not shown) ejection CD 2, get back to step SP2 then.

In contrast, if the user provides the instruction of ejecting outside the CD 2, then microcomputer 4 just proceeds to SP6 from step SP5, and at this, it will judge that user's instruction is record (REC), reproduction (PB) or cuts off.If user's instruction is " PB (reproduction) ", then microcomputer 4 just proceeds to SP7 from step SP6, and at this, it will reproduce the file from CD 2, get back to step SP5 then.

If user's instruction is " REC (record) ", microcomputer 4 just proceeds to SP8 from step SP6, and at this, it will get back to step SP5 then motion or static image recording to CD 2.Importantly to be described as follows a bit, when CD 2 has the UDF that defines therein by so-called final processing and VMG district, microcomputer 4 will be skipped recording process and to step SP5, this is because CD 2 is handled, and make them can't record data.Even finally be treated at CD 2 under the situation of erasable DVD-RW, microcomputer 4 also can come the line data record of going forward side by side of the data content on the erasing CD-disc 2 according to user's affirmation.

When user's instruction is " cut-out ", microcomputer 4 will proceed to SP9 from step SP6, and at this, it will turn-off the power supply of CD drive 1, get back to step SP4 then, and at this, it will withdraw from record or reproduction process.

In the recording process of one of said process, if CD 2 is DVD-R, then microcomputer 4 will adopt the INC method come motion or static image file record on the CD 2.On the other hand, if CD 2 is DVD-RW or DVD-RAM, then microcomputer 4 will adopt the ROW method come motion or static image file record on the CD 2.

Fig. 6 A is used to illustrate with the INC method image file of motion or static image file are recorded file logging is not arranged as yet in CD 2 wherein, i.e. blank disc to the figure shown in Fig. 6 K.Renewal obtains and is kept at RMA information the built-in storer from CD 2, as shown in Figure 6A, and microcomputer 4 reservation Rzone 1.

In order to write down motion pictures files, as shown in Figure 6A, microcomputer 4 will be similarly be preengage Rzone 2 and sightless Rzone by upgrading RMA information, and the video data journal that will be made up of real data is in sightless Rzone, so that generation VTSTT is VOBS.Similarly, provide instruction when stopping to write down the user, shown in Fig. 6 B, microcomputer 4 will produce VTSI BUP, and shown in Fig. 6 C, generation VTSI and VTSM VOBS are so that produce a VTS.According to consequent VTS, microcomputer 4 is stored in the management information of data in its storer, and upgrades the RMA information that is stored in the storer.

In order to write down next motion pictures files, microcomputer 4 will upgrade the RMA information that is kept in the storer similarly, so that reservation Rzone 2 and sightless Rzone, then with the real data journal in sightless Rzone, and produce VTSTT VOBS and VTSI BUP and VTSI and VTSM VOBS.The generation of data is corresponding therewith, and microcomputer 4 records the management information of these data in the storer, and upgrades the RMA information that is kept in the storer.

When adopting the INC method to write down moving image, as in the INC of routine method, microcomputer 4 is with the journal title.Load the final as yet CD of handling 2 and will data supplementing when recording on the CD 2, microcomputer 4 will be used in obtain among the step SP2 of Fig. 5 and be kept at RMA data in the storer, end from existing title, carry out similar operation, thereby record is as the moving image of imaging results with appending.

On the other hand, in the processing of final processing CD 2, microcomputer 4 will import section and derive section so that define from by producing UDF and the VMG of Rzone 1 in the management information that produces and be kept at as upper type the storer.Certainly, with data supplementing when recording as yet on the final CD of handling 2, microcomputer 4 will produce UDF and the VMG data that have title now according to resulting VTSI and VTSMVOBS in the step SP3 of Fig. 5 on CD 2.

Utilize above-mentioned operation, CD drive 1 writes down motion pictures files as in the INC of routine method with the DVD video format.

When the user indicates the record rest image, microcomputer 4 is at first preengage sightless district by the RMA that renewal is kept in its storer, so that journal is as the static picture document (the reference letter E F shown in Fig. 6 E among Fig. 6 is represented) of extendfile.In addition, EF is corresponding with the record static picture document, information is kept in its built-in storer, and microcomputer 4 produces middle management information with order, so that the temporary control and education static picture document is till final processing.

In addition, after the static picture document that has write down institute's requested number, when the user provides order fulfillment record static picture document, microcomputer 4 will be closed sightless Rzone by the RMA that renewal is kept in the storer, shown in Fig. 6 F, with Rzone 3 in advance in the district that continues with static picture document.Microcomputer 4 also will become the form be used to record on the CD 2 to the intermediate management information translation that is kept in the storer, and, shown in Fig. 6 G, the management information of centre is recorded among the Rzone3.

Be noted that, for reading extendfile, intermediate management information is necessary, it records by the address of extendfile and size, attribute expansion and with extendfile, and date and time on the CD 2 forms, and, to shown in the 7B, for each attribute of continuous recording extendfile, intermediate management information collectively writes down as Fig. 7 A.In other words, shown in Fig. 7 B, intermediate management information is made up of file control information DJ, the DM7 of leader and representation attribute and DM4.For example, shown in Fig. 7 A, if write down file FJ1, FJ2 and the FJ3 of three jpeg formats according to user's instruction, the file FM71 and the FM72 of two MPEG-7 forms have been write down then, and the file FM41 and the FM42 of two MPEG-4 forms have been write down again, leader in the intermediate management information then can show the file that has write down these three types in CD 2, and subsequently file control information DJ, DM7 and the address of DM4.Be noted that also mark " DJ ", " DM7 " and " DM4 " are illustrated respectively in defined file control information among JPEG, MPEG7 and the MPEG4.

Shown in Fig. 7 C, in each file, write down the file control information DJ of each attribute among management information DFJ1, DFJ2 and the DFJ3 each.And shown in Fig. 7 D, date and time of corresponding extended file attributes, address AD DR, size, record etc. is distributed to management information DFJ1 on each file.

Be noted that, in this embodiment, in the time will using on the CD drive 1 as extendfile, for each attribute that has write down the CD 2 of data by CD drive 1 thereon, with the file control information DJ that only produces shown in Fig. 7 B based on the static picture document of JPEG.

Like this, even under any other file logging that will be except motion pictures files situation to the CD 2, microcomputer 4 also can record the management information of file and file in the program area on the CD 2 together.At this moment, if the file that records on the CD 2 is a motion pictures files, then microcomputer 4 will be controlled, and the backup information that makes management information, file and management information is record sequentially.If record file on the CD 2 is static picture document outside the motion pictures files, then microcomputer 4 will be controlled, make the management information of log file and file sequentially, thereby come management conversion recording of information form according to the attribute of corresponding file.

As mentioned above, if write down intermediate management information D K like this, then microcomputer 4 will store intermediate management information D K in its internal memory and with it into and be kept at the there.If microcomputer 4 has write down intermediate management information D K in this way, and then the record static picture document, so, it will be under the instruction of user's end record, similarly journal extendfile and write down intermediate management information D K.

On the other hand, in order then to write down motion pictures files, shown in Fig. 6 H, microcomputer 4 will be preengage Zone and sightless Rzone, so that VTSTT VOBS and VTSIBUP and VTSI and the VTSM VOBS of definition shown in Fig. 6 I.Like this, shown in Fig. 6 J, microcomputer 4 will continue after intermediate management information D K and write down a VTS.

Operation above utilizing, the combination of the static picture document of the non-DVD video format of CD drive 1 record and the management information of static picture document, and the motion pictures files of DVD video format.Like this, in the CD drive of only supporting the DVD video format of routine, when on the CD 2 that writes down like this, searching the real-time data record district according to RMA, can only detect VTSI and VTSTT VOBS, yet the intermediate management information of the extendfile of the rest image that does not define by any way and this extendfile will can not be identified as any significant file as VTS management information.On the other hand, in the CD drive of the extendfile of supporting the above-mentioned type, can discern the intermediate management information of extendfile and this extendfile of VTS management information, rest image.

Like this, microcomputer 4 will write down extendfile and can not influence the reproduction of the moving image in the CD drive of routine.

Like this, in user indication when final processing wherein records the CD 2 of extendfile as upper type, shown in Fig. 6 K, microcomputer 4 will be from the reference admin table and the management information (VTSI and VTSTT VOBS) of all titles of producing like this and whole generation UDF data the intermediate management information of extendfiles, and with these UDF data recording to CD 2.In addition, microcomputer 4 is generation VMG data from the management information (VTSI and VTSTT VOBS) of all titles only, and with these data recording to CD 2.Importantly will be described as follows a bit: UDF and VMG data are to produce according to the intermediate management information or the similar information that are kept in the storer.Write down in this manner after UDF and the VMG, microcomputer 4 will define and import section and derive section.Also be noted that microcomputer 4 record UDF and VMG data, definition imports section and derives section, and record intermediate management information, and these are all finished in DVD signal processor 14 by exporting corresponding data.

Therefore, in this embodiment, the UDF data that computer management is used will comprise the management information that is used to discern with the access extendfile, will not comprise the information relevant with extendfile but be used for the VMG data that DVD reproduces management.As shown in Figure 8, microcomputer 4 is used for the UDF data of supervisory computer with reproduction, producing UDF in the file that separates in the level layer identical with the DVD title, thereby only shows extendfile.For top with reference to Fig. 7 A to the described intermediate management information D of Fig. 7 D K, microcomputer 4 will produce does not have filename, the UDF of the address information of address etc. as described.Should be noted that microcomputer 4 will produce UDF certainly, so that can as access title VTSI, VTSM VOBS etc., come each extendfile of access.Like this, in this embodiment, when active computer reproduces CD 2, just the file of interim intermediate management information can be become the sightless file of user, this document is nonsensical by computer vision reappear theory CD 2 time, thereby can correspondingly improve the operability of CD drive 1.

Like this, by with the VMG data recording to CD 2, conventional DVD CD drive just can only read the motion pictures files that is recorded on the CD 2.In contrast, in CD drive 1, microcomputer 4 obtains UDF and VMG data in the step SP3 of Fig. 5, so that for access provides system's control based on each extendfiles of UDF data, thereby and reproduces extendfile.Should be noted that in Fig. 8 " root (Root) " is root directory, " VIDEO TS " is the motion pictures files folder, and " DSC " is extension folder." DSC0001 " and " DSC0002 " is respectively extendfile.

Fig. 9 A is used to illustrate the record based on ROW that compares with the record based on INC shown in Figure 6 to the figure shown in the 9H.If CD 2 is DVD-RW or DVD-RAM, microcomputer 4 will adopt the ROW method to write down motion pictures files and extendfile.More particularly, as such in the conventional system shown in Fig. 9 A, in order to write down motion pictures files, microcomputer 4 is preengage a district by filling in the RMA management, and write down VTSTT VOBS and VTSI BUP there, and shown in Fig. 9 B, preengage next district by filling, and shown in Fig. 9 C, once more at section start definition VTSI and VTSM VOBS.Like this, microcomputer 4 will record a VTS on the CD with the ROW method.

In order to continue to write down a moving image, microcomputer 4 will repeat and top similar operation, so as in conventional system sequentially record header and final processing CD.

On the other hand, shown in Fig. 9 D, in order to write down extendfile, if preengage a district by filling, then microcomputer 4 will be from the top in this district, in this district, and record intermediate management information D K is again by filling the next header record of reservation district extendfile EF journal.Should be noted that record extendfile EF is identical with the INC method with the method for intermediate management information D K, except they are to be recorded in the top of the recording areas of preengaging by filling and to preengage next header record district by filling.

In order to continue to write down an extendfile, microcomputer 4 will repeat to write down like this extendfile EF and intermediate management information D K, and by filling district of reservation.For the extendfile record motion pictures files that continues, shown in Fig. 9 E and 9F, microcomputer 4 will be in the district that continues with the district of having filled record VTSTT VOBS and VTSI BUP, by filling the next district of reservation, and as the motion pictures files record motion pictures files that continues, once more at section start definition VTSI and VTSM VOBS.Like this, just a VTS has been recorded on the CD shown in Fig. 9 G.

Therefore, CD drive 1 can be by DVD video format record motion pictures files, and also can write down the combination of the intermediate management information of the static picture document of non-DVD video format and this document, and can not influence reproducing motion pictures files in the CD drive of routine.

Be noted that in order to write down extendfile in the manner described above, the management information that microcomputer 4 will write down and preserve each extendfile in its internal memory, this is as top illustrated with reference to Fig. 6.

On the other hand, as in the INC method, for the final CD 2 of handling, microcomputer 4 will produce UDF and VGM data, and they are recorded in the district of preengaging by filling, so that produce UDF and VGM, and definition imports section and derives section.Like this, even utilize the ROW method, as in the INC method, the energy records management information, so that can read the motion and standstill image file from the CD of supporting extendfile by enough some computing machines, and, with some routine, can only read moving image towards the CD drive of DVD.

Above Figure 10 shows with reference to the operating process of the recording process of Fig. 6 and Fig. 9 explanation.When this recording process of beginning, microcomputer 4 proceeds to SP12 from step SP11, and at this, it will judge what user's indication will do, and is the record motion pictures files, still writes down static picture document, or final the processing.

When user's indication will be write down motion pictures files, microcomputer 4 proceeded to SP13 from step SP12, and at this, it will judge whether the user has indicated opening entry.If the judged result at step SP13 negates that microcomputer 4 is with the operation of repeating step SP13.If top judged result is sure, microcomputer 4 will proceed to SP14 from step SP13, and at this, with reference to Fig. 6 and Fig. 9 explanation, it will write down real data as top.In addition, microcomputer 4 enters step SP15, and at this, it will be judged whether the user has indicated and stop record.If the judged result in step SP15 negates that microcomputer 4 will be got back to step SP14.Like this, microcomputer 4 will repeat the operation in step SP14, SP15, and journal real data in step SP14 once more.If top judged result is sure, microcomputer 4 will be finished the record of VTSTTVOBS data with the record of existing real data.

Subsequently, microcomputer 4 enters step SP16, at this, it will be in CD 2 sequential definition VTSI BUP, VTSI and VTSM VOBS district, thereby write down a VTS, enter step SP17 then, at this, it will withdraw from this recording process.

On the other hand, if user's instruction is the record static picture document, microcomputer 4 will proceed to SP18 from step SP12, and at this, it will judge whether the user has indicated opening entry.If the judged result in step SP18 negates that microcomputer 4 will repeat the operation in step SP18.In contrast, if top judged result is sure, microcomputer 4 will proceed to SP19 from step SP18, and at this, as top illustrated with reference to Fig. 6 and Fig. 9, it will write down the extendfile of static picture document.And then microcomputer 4 proceeds to step SP20, and at this, it will be judged whether the user has indicated and stop record.If the judged result in step SP20 negates that microcomputer 4 will be got back to step SP19.Like this, microcomputer 4 will repeat the operation in step SP19, SP20, and journal static picture document in step SP19 once more.If top judged result is sure, microcomputer 4 is with regard to the end record static picture document and enter step SP21, and at this, it will write down intermediate management information, enter step SP17 then, and at this, it will withdraw from this recording process.

When user's the instruction data that to be record relevant with final processing CD 2, microcomputer 4 will proceed to SP22 from step SP12, and at this, it will judge whether the user has indicated opening entry.If the judged result in step SP22 negates that microcomputer 4 will repeat the operation in step SP22.If top judged result is sure, microcomputer 4 will proceed to SP23 from step SP22, at this, illustrate that with reference to Fig. 6 and Fig. 9 it will finally handle this CD 2, enter step SP17 then as top, and at this, it will withdraw from this process.

Figure 11 illustrates the operating process that is contained in reproduction process shown in Figure 6.When this reproduced process in beginning, microcomputer 4 proceeded to SP32 from step SP31, and at this, it will be judged whether the user has indicated and read motion pictures files or static picture document.

If user's indication is a reproducing motion pictures files, microcomputer 4 will proceed to SP33 from step SP32, and at this, it will be judged whether the user has indicated and begin to reproduce, if the result who judges negates that microcomputer 4 will repeat the operation in step SP33.If top judged result is sure, microcomputer 4 will proceed to SP34 from step SP33, and at this, it will provide system control, so as to reproduce by the user with reference to being kept at management information in the storer motion pictures files of appointment.

In other words, if CD 2 is final of handling, microcomputer 4 just detects the address of corresponding file according to the VMG data in the internal memory that is kept at it, and from then on each parts of pilot light disk drive 1 read file in the address.On the other hand, if CD 2 is not final of handling, microcomputer 4 will be according to being kept at the address that title VTSI in the storer and VTSTT VOBS detect corresponding file, and from then on each parts of pilot light disk drive 1 read file in the address.

By after indicating reproduction as upper type, microcomputer 4 will proceed to step SP35, and at this, it will be judged whether the user has indicated and stop to reproduce.If the judged result in step SP35 negates that microcomputer 4 will be got back to step SP34.Like this, microcomputer 4 will repeat the operation in step SP34, SP35, and read the motion pictures files by user's appointment in proper order once more in SP34.On the other hand, if top judged result is sure, microcomputer 4 will stop reproducing operation, and proceed to step SP36, and at this, it will withdraw from the reproduction process.

On the other hand, if user's instruction is to read extendfile, microcomputer 4 will proceed to SP37 from step SP32, and at this, it will be judged whether the user has indicated and begin to reproduce.If the result who judges negates that microcomputer 4 is with the operation among the repeating step SP37.In contrast, if the result who judges is sure, microcomputer 4 will proceed to SP38 from step SP37.

If CD 2 is final of handling, microcomputer 4 will detect the address of corresponding file according to the UDF data in the storer that is kept at it, and from then on each parts of pilot light disk drive 1 read this file in the address.On the other hand, if CD 2 is not final of handling, microcomputer 4 will detect the address of corresponding file according to the intermediate management recording of information in the storer that is kept at it, and from then on each parts of pilot light disk drive 1 read file in the address.

After indication is reproduced in the manner described above, microcomputer 4 will proceed to step SP39, and at this, it will be judged whether the user has indicated and stop reproduction.If the judged result in step SP39 negates that microcomputer 4 will be got back to step SP38.Like this, microcomputer 4 will repeat the operation in step SP38, SP39, and read the static picture document by user's appointment in proper order once more in SP38.In contrast, if top judged result is sure, microcomputer 4 just stops reproducing operation, and proceeds to step SP36, and at this, it will withdraw from the reproduction process.

Like this, in this embodiment, microcomputer 4 provides the management information generation device, in order to produce the management information of the file that will write down, in addition, DVD signal processor 14, random access memory 15, AFE (analog front end) piece 16, amplidyne generator 18, shaven head 19 and the spindle motor 20 common pen recorders that form record in the program area on the CD 2 together in order to the management information with file and file.Microcomputer 4 also provides control device, operation in order to control and management information generating apparatus and pen recorder, it also and compression/extension piece 6, heading information processor 7, DVD signal processor 14, random access memory 15, AFE (analog front end) piece 16, amplidyne generator 18, shaven head 19 and spindle motor 20 form transcriber together, be recorded in the file that management information in the CD 2 is come each attribute of reading and recording in CD in order to basis with file.

Bring into play function as described below with reference to the CD drive 1 of the described structure of Fig. 4 above:

When the user is loaded into CD 2 in the CD drive 1 of having started, when perhaps starting the CD drive 1 that has the CD 2 that is loaded in the CD drive 1, microcomputer 4 control DVD signal processors 14 and amplidyne generator 18 are with drive thread motor 21, so that shaven head 19 is shifted to the inner periphery of CD 2.And then, laser beam is projected on the CD 2 from shaven head 19.Detect back light with shaven head 19, and sequentially it is handled by AFE (analog front end) piece 16 and microcomputer 4.By means of DVD signal processor 14 and amplidyne generator 18, carry out tracking Control and focus control with 4 pairs of shaven heads of microcomputer 19.In addition, handle the back light that detected with DVD signal processor 14, so as from the CD 2 reading of data.In CD drive 1, utilize microcomputer 4 and obtain the various information that write down along the inner periphery of CD 2, and they are kept in the storer that is built within the microcomputer 4 by top a series of operation.

If CD 2 is the read-only optical discs that form by compacting (stamping), or a CD that has wherein only write down the final processing of motion pictures files, microcomputer 4 will by above-mentioned a series of operation obtain along CD 2 inner peripherys records, as the VMG data of the management information of DVD player.Like this, in CD drive 1, when the user indicates reproduction CD 2, just can utilize DVD signal processor 14 and amplidyne generator 18 and come drives spindle motor 20 according to the VMG data, so that shaven head 19 is moved on the address of user's specified title (search operation), and shaven head 19 is carried out tracking Control and focus control according to the back light that detected, sequentially handle the back light that detected by DVD signal processor 14, heading information processor 7 and compression/extension piece 6, so that read the video data of forming by moving image.More particularly, handle read signal to produce read data with AFE (analog front end) piece 16, this read signal is the result that back light detects, and its grade (level) is corresponding to the hole on the CD 2 string and change, with 14 pairs of read datas of DVD signal processor decode, cancellation interlace (deinterleaved) and error correction.To offer heading information processor 7 through the read data of error correction, and, from data, remove leader and leader is reported to microcomputer 4 at this.And then, read signal is offered compression/extension piece 6, and it is decomposed into video data and voice data with multiplexer 10.By video processor 8 video data is discharged (release) under the MPEG-compressive state and come out, and it is presented on the monitor 12 or by video/audio encoder 13 offers external unit.On the other hand, come the extended audio data, offer the usefulness of monitor 12 then, perhaps offer external unit by video/audio encoder 13 for monitoring with audio process 11.

If CD 2 is recordable blank discs, so, when being loaded into CD 2 in the CD drive 1 or when starting CD drive 1, microcomputer 4 with access CD 2 so that from CD 2, obtain the RMA data.In CD drive 1, when the user selects moving image drainage pattern and VMG, if CD 2 is DVD-R (as shown in Figure 6), microcomputer 4 is kept at renewal the RMA data in its storer, so that come to preengage some districts for UDF and VMG by reservation Rzone 1.If CD 2 is DVD-RW (as shown in Figure 3), microcomputer 4 will upgrade the RMA data similarly, so that for UDF and VMG preengage some districts, and by filling VTSI and VTSM VOBS for first VTS to preengage some districts.

In the case, when the user indicates opening entry, provide video and voice data by video input block 3 and audio frequency input block 5 orders, and when coming audio compressed data, come compressed video data by video processor 8 with the MPEG technology by audio process 11.And then, by the video and the voice data of multiplexer 10 multiplexed such compressions, then, leader is added in the multiplexed data with heading information processor 7.In DVD signal processor 14, in multiplexed data, add error correction code subsequently, and multiplexed data is interweaved (interleave) and encodes.According to The results of data processing, AFE (analog front end) piece 16 will be projected on the CD 2 by shaven head 19 laser beam of launching a certain amount of.Like this, just on CD 2, sequentially form many holes, so that sequentially write down the sport video data of forming by moving image.

In CD drive 1, when user's indication stops to write down, microcomputer 4 will stop at sequence of operations in compression/extension piece 6 grades, so that end the record of video data, then, the management information of motion pictures files of record is like this recorded on the CD 2.In other words, in CD drive 1, microcomputer 4 will wait according to address, file size, the record date of motion image data and produce management information, management information is offered DVD signal processor 14, and it is recorded on the CD 2, the management information video data that continues is recorded, defines VTSI BUP district therefrom.Then, if CD 2 is DVD-RW,, thereby make the district of shaven head 19 existing VTSI of search and VTSM VOBS just by filling VTSI and the VTSM VOBS district that defines next VTS.Similar management information is offered DVD signal processor 14, and it is recorded on the CD 2, so that the VTSI and the VTSM VOBS district of definition intention.

In CD drive 1, the video data that a header record is made up of moving image.Like this, in CD drive 1, in order to write down motion pictures files, come records management information and file by the DVD video format, wherein, the management information of forming by VTSI, the management information of forming by VTSM VOBS, motion pictures files and be to place continuously by the management information that VTSI BUP forms.

When the user indicates the record moving image, repeat similar operation so that title is sequentially recorded on the CD 2.If in a manner described such title is sequentially recorded on the not final as yet CD of handling, and this CD is loaded in the CD drive 1, that just passes through with reference to RMA data scanning CD 2, at first obtain the management information and the RMA data that write down with title, and will being kept in the storer that is built in microcomputer 4, and the title of record from continuing by the end that scans CD 2 detected titles with the management information that title writes down.

In CD drive 1, in a manner described with header record to CD 2 and user when indicating final processing CD 2, the management information that is recorded in together in the storer with regard to basis and title produces UDF and VMG data, and UDF and VMG data recording in the inner periphery district of definition on the CD 2, and also definition imports section and derives section.Like this, just can set the CD that reproduces with the DVD player of only supporting the common DVD form.

On the other hand, if the user has selected the rest image logging mode, so, UDF and VMG district will be defined within the blank disc, just as by updating stored in the RMA in the storer and writing down moving image by filling.In CD drive, to the rest image pattern, and be operator scheme based on the data compression of JPEG with the mode transitions of compression/extension piece 6 with the mode transitions of imaging device.

In the case, when the user indicates the opening entry rest image, just the video data compression that will be made up of the rest image that provides from video input block 3 by the video processor 8 of compression/extension piece 6 is a jpeg format, with the voice data that provides by audio process 11, carry out multiplexed then with multiplexer 10.Like this, in CD drive 1, the video data that is made of rest image, but not any video data that is made of moving image just as when the record moving image, are provided to be used for record, and are sequentially recorded on the CD 2.

In CD drive 1, when the record moving image, the district that at first defines VTSI and VTSM VOBS is so that the record real data still, for the record rest image, writes down the real data of being made up of rest image and then do not preengage such district.When the user indicates the record rest image, in the manner described above rest image is subsequently recorded on the CD 2.When each record, the address of each file is recorded in the storer of microcomputer 4.

In CD drive 1, when the user changes operator scheme and stops the record of rest image, perhaps when the static picture document of institute's requested number has recorded on the CD, to the provisional intermediate management information of the management information of being made up of the information such as address that are kept in the storer when wanting always to use final the processing be recorded in the continuum of using for a plurality of static picture documents.Like this, in CD drive 1, for record other file except any motion pictures files, will come the management information of log file and file according to the order of file and management information, and select the form of log file and management information according to the attribute of the file that will write down.

As mentioned above, CD drive 1 can will be not that the static picture document that defines with the DVD video format records on the CD 2 yet.When the CD of the static picture document that record like this is wherein arranged being loaded in the CD drive of only supporting the DVD video format, search the management information that detects according to the record of the DVD video format such as VTSI during by loading tray, and read VTS according to this management information.Like this, so the static picture document of record and the management information of file can not influence reading of any moving image.Therefore, any common DVD player just can read motion pictures files from the CD of motion pictures files that record like this is wherein arranged.

In contrast, also support the CD drive of the file outside the moving image also can read static picture document for one.In other words, loaded therein in the CD drive 1 of above-mentioned CD 2, to at first search CD 2,, and this management information will be kept in the storer of microcomputer 4 so that read the intermediate management information of VTS and VTSM VOBS data and static picture document from CD 2.

Like this, just can under being provided at user's indication, the user be recorded in the motion and standstill image header in the CD 2.In addition, when moving image was read in user's indication, CD drive 1 just can be read motion pictures files according to VTS and VTSM VOBS data, just as described about read-only optical disc.

On the other hand, when static picture document is read in user's indication, to detect the address of file etc. according to the intermediate management information in the storer that is kept at microcomputer 4, and, be similar to the operation of reading in the moving image by those then and handle these data according to the result who the detects data of reading and recording in CD 2 sequentially.In CD drive 1, when handling read data, in order to handle the read data that comprises rest image, change the operation of video processor 8 with microcomputer 4, so that expansion is according to the video data of JPEG compression, and supervision comprises the video data of rest image on monitor 12, and and then on video/audio encoder 13, provide these video datas to external unit.

Usually, the size of static picture document is smaller than motion pictures files.Yet, as shown in Figure 7, in CD drive 1, for a plurality of files produce and write down as the intermediate management information of management information.Like this, in CD drive 1, owing to write down the extendfile of forming by such static picture document or similar file, but the minimizing of the recording areas that causes owing to the record management file with regard to energy minimization.

Similarly, for each file type as file attribute, the intermediate management information of a plurality of files is collective's records, therefore, can simplify and search and the final operation of handling (this will describe in detail in the back).

By above-mentioned operation, CD drive 1 is operated by the user, so that the motion and standstill image file is sequentially recorded so-called blank disc, wherein only write down moving image but the final as yet CD of handling and wherein write down the motion and standstill image file but the final as yet CD of handling.

On the other hand, when the final in a manner described processing of user indication wherein records any above-mentioned CD of motion and standstill image, according to management information the storer that obtains and be kept at microcomputer 4 from CD and intermediate management information, and produce the UDF data of using for computing machine according to the management information and the intermediate management information that produce by record motion and standstill image and be kept in the storer, in the predefined district of UDF data recording to the CD 2.Only the management information according to motion pictures files produces the VMG data of using for DVD player, and similarly it is recorded on the CD 2.
